WOW! Nice story. I’m running very similar project for free and for fun. Also this is usually happening to me every day. Besides other things I’m providing also website checks, so almost every second registration is used to wake up bots like repl.co or minecraft bots hosted on such sites. Life isn’t easy, right? :D anyway it is still the fun to run such service and I understand why author want it alive for a such long time :) when you want to try something similar with few more features, give a try to hostbeat.info
